Manchester United's decision to sign Casemiro is a good one, according to club legend Roy Keane.
The Irishman was speaking before their Premier League game against Liverpool on Monday, which they won 2-1.
Casemiro was at the stadium for the match, but was not registered in time to participate.
"I think he's a good signing," Keane told Sky Sports.
"They've paid a lot of money, he's 30 years of age, he's got a five-year contract.
"If you're a player out there and Man United come looking for you, you know you're going to get a great deal.
"It's a start but they need some more, they need more help.
"The problem is for any player coming into Man United now, as good as they are, they're coming into a bad dressing room, they're coming into a bad group of players.
"We keep mentioning it in the last year or two, these players don't want to run, they don't seem like a good group. That's a problem for any player, however good they are.
"They're desperate, but I think he is a quality player. You can look at the bigger picture and go obviously it's a lot of money and a long contract, the agents out there must be delighted dealing with Man United, but when you're desperate you've got to pay over the odds."
